Abstract
A multi-component inorganic capsule anchoring system can be used for chemically fastening anchors, bolts, screw anchors, screw bolts, and post-installed reinforcing bars in mineral substrates. The multi-component inorganic capsule anchoring system contains a curable powdery ground-granulated blast-furnace slag-based component A, and an initiator component B in aqueous-phase for initiating a curing process. The powdery ground-granulated blast-furnace slag-based component A contains further silica dust. The component B contains an alkali-silicate component and optionally a plasticizer.
